Description

[Technical Field]

[0001] The present invention relates to the field of power tools, and more particularly to a battery pack with magnetic attraction function. [Background technology]

[0002] Power tools are handheld tools that use electricity as a power source to drive a working head via a motor or power line. These types of tools offer significantly improved work efficiency compared to manual tools. They eliminate the constraints of power lines and allow power tools to be used outdoors or in places without electrical outlets. To this end, mobile power sources for power tools, such as battery packs, have been introduced. By connecting the battery pack to the power tool, the battery pack can power the power tool. However, with existing power tools, the power tool must be stored in a bag after use and then removed from the bag when it is used again. When working at heights, for example, both hands can only use one power tool at a time. In such cases, if a user needs to constantly switch between power tools with two functions, the power tool must be repeatedly removed from the bag, which is time-consuming and reduces efficiency. Therefore, there is a need for a battery pack with a magnetic attraction function that allows users to quickly switch between different power tools without having to repeatedly remove the power tool from the bag. Summary of the Invention [Problem to be solved by the invention]

[0003] The object of the present invention is to provide a battery pack with a simple structure, a magnetic attraction function that can be quickly switched when working with different power tools, and does not require repeated removal from a bag. [Means for solving the problem]

[0004] The object of the present invention is achieved as follows:

[0006] Furthermore, the magnetic attraction device is a magnetic attraction part formed on the bottom surface of the battery pack body, and when the magnetic attraction part approaches a metal object, the magnetic attraction part can be attracted to the metal object.

[0007] Furthermore, the magnetic attraction device is connected and / or engaged with the outer surface of the battery pack body, and the magnetic attraction device is a magnet.

[0008] Furthermore, the battery pack body is provided with a case that is detachably connected to the battery pack body, and when the case and the battery pack body engage with each other, a magnetic attraction device is provided between the battery pack body and the case, thereby restricting the magnetic attraction device from detaching from the battery pack body.

[0009] Furthermore, the case has a plurality of through holes, and the number of the magnetic attraction devices matches the number of the through holes. When the case is connected to the battery pack body, a portion of the magnetic attraction device is exposed from the surface of the case through the through holes.

[0010] Furthermore, the battery pack body is provided with a plurality of mounting grooves on the underside of the battery pack body, and the number of magnetic attraction devices is the same as the number of mounting grooves, and the magnetic attraction devices can be placed in the mounting grooves.

[0012] Furthermore, the case may be fitted with a magnetic shield shell that is detachably connected to the battery pack body. When the magnetic shield shell is connected to the battery pack body, the case is located between the battery pack body and the magnetic shield shell. In this case, the magnetic shield shell can weaken or shield the magnetic attraction force of the magnetic attraction device against metal objects.

[0013] Furthermore, a band hole is further drilled in the magnetic shield shell, and a connection band is provided in the band hole, and the tip of the connection band passes through the band hole and is wrapped around the battery pack body and the power tool, and is connected to the distal end of the connection band.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will be further described below with reference to specific examples.

[0019] The battery pack with magnetic attraction function comprises a battery pack body 1 and a power pack installed in the battery pack body 1, the battery pack body 1 being capable of supplying power to an electric tool via the power pack, and a magnetic attraction device 3 capable of adsorbing to a metal object being provided on and / or inside the battery pack body 1.

[0020] The present invention provides a battery pack with a magnetic attraction function that can improve work efficiency and make work easier for workers. A magnetic attraction device 3 is additionally installed on the battery pack, which can be attached to a metal object or device through the magnetic attraction device 3. After attachment, the power tool is suspended or leaned relative to the device, allowing the user to take out another power tool from the bag and use it. When switching, the user can simply attach the battery pack with the suction function held in their hand to the device, and directly remove the previously attached power tool for use. Compared to the conventional tool storage state, the tools are always available for use, improving work efficiency and speeding up operation.

[0021] Preferably, the magnetic attraction device 3 is a magnetic attraction part molded on the underside of the battery pack body 1, and when the magnetic attraction part approaches a metal object, it can be attracted to the metal object. In the present invention, the magnetic attraction part is designed directly on the underside of the battery pack body 1, and the surface of the case 4 is made of a material that can attract metal objects, so that the battery pack body 1 can be directly attracted to metal objects at will, and the integrated design is more convenient.

[0022] Preferably, the magnetic attraction device 3 is connected to and / or engaged with the outer surface of the battery pack body 1, and the magnetic attraction device 3 is a magnet. The present invention uses a split design to install the magnetic attraction device 3 with magnetic attraction force on the outer surface of the battery pack body 1. The magnetic device 3 is a commonly available magnet on the market and is easy to replace, so it can maintain its strong attraction ability. The present invention uses magnetic attraction to enable workers to attach power tools to any steel frame. The magnetic attraction method allows the battery pack to be instantly attached to the metal surface without any additional operation, and the removal and placement speed is very fast, truly achieving one-touch attachment and one-pull separation. Furthermore, magnetic attraction is a physical contact that leaves no adhesive stains, scratches, or residue on the metal surface. It is resistant to dust, oil, and moisture, has low cost, and has a long life.

[0023] Preferably, the battery pack body 1 is provided with a case 4 that is detachably connected to the battery pack body 1, and when the case 4 and the battery pack body 1 are engaged with each other, the magnetic attraction device 3 is provided between the battery pack body 1 and the case 4, thereby preventing the magnetic attraction device 3 from falling and improving safety.

[0024] Preferably, the case 4 has a plurality of through holes 5, and the number of the magnetic attraction devices 3 is the same as the number of the through holes 5. When the case 4 is connected to the battery pack body 1, a part of the magnetic attraction device 3 is exposed from the surface of the case 4 through the through holes 5, thereby exposing the internal magnetic attraction device 3 and enhancing the adsorption ability of the magnetic attraction device 3.

[0025] Preferably, the battery pack body 1 is provided with a plurality of mounting grooves 2 on the underside of the battery pack body 1, and the number of magnetic suction devices 3 is the same as the number of mounting grooves 2. By arranging the magnetic suction devices 3 at corresponding mounting positions within the mounting grooves 2, the suction ability can be increased, so that the power tool can be more firmly attracted and prevented from falling due to light contact, and since they are installed on the underside of the battery pack body 1, it is also possible to hang the power tool upside down.

[0026] Preferably, the battery pack body 1 is provided with at least one screw hole 6 therein into which a connecting screw is provided, and the case 4 is provided with a drilled hole 7, and the connecting screw passes through the drilled hole 7 and is threadedly connected to the screw hole 6, thereby restricting the case 4 from being separated from the battery pack body 1 and ensuring stable attachment, and the connecting screw restricts the case 4 from being detached from the battery pack body 1, thereby preventing the magnetic attraction device 3 from being detached.

[0027] Preferably, the case 4 is fitted with a magnetic shield shell 8 which is detachably connected to the battery pack body 1. When the magnetic shield shell 8 is connected to the battery pack body 1, the case 4 is located between the battery pack body 1 and the magnetic shield shell 8. In this case, the magnetic shield shell 8 can weaken or shield the magnetic attraction force of the magnetic attraction device 3 against metal objects, and can also serve as a partition, attracting other items when placed in a bag. When taking out the power tool, it is more convenient to prevent other tools from being attracted to the tail of the magnetic attraction device 3. The magnetic shield shell 8 can be engaged with the case 4, providing a convenient installation method.

[0028] Preferably, the magnetic shielding shell 8 is further provided with a band hole 9, within which a connecting band is provided. The tip of the connecting band passes through the band hole 9 and is wound around the battery pack body 1 and the power tool, and is connected to the distal end of the connecting band, thereby securing the battery pack body 1 to the power tool body and preventing the battery pack body 1 from easily falling off. In the present invention, the band hole 9 is further provided, and the connecting band passes through the band hole 9 and is wound around the battery pack body 1 to bind it, thereby preventing the battery pack body 1 from coming off the power tool. In the conventional battery pack and power tool, the battery pack is connected only by a sliding snap, which can cause the battery pack to come off in the event of an accident during operation. In the present invention, after the battery pack body 1 and power tool are bound, the two cannot be separated. Before operation, one end of the connecting band is passed through the band hole 9 and wrapped around the side of the battery pack body 1 around the lower base of the power tool, and finally the other end of the connecting band is wrapped around the base, and finally the proximal end and distal end connecting bands are tightened relative to each other.

[0029] Preferably, a plurality of protrusions 10 are further provided on the surface of the magnetic shield shell 8, and the band holes 9 pass through the protrusions 10.

[0030] The above embodiments are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention. Therefore, any equivalent modifications made based on the structure, shape and principle of the present invention should be included within the scope of protection of the present invention.
